APPARATUS FOR IRRIGATING STREETS.

Specification of Letters Patent No. 32,278, dated May 14, 1861.

To all whom fit may concern:

Be it known that I, JAMES I. ELLICCTT, of the city of Washington, District of Columbia, have made certain new and useful Improvements for Washing and Irrigating Streets.

The nature of my invention consists in inleting a grooved piece of timber or other known substance in the crown of the arch of the street for its entire length,1in which a double perforated pipe connected to the great water mains by suitable pipes and stop cocks or regulators is laid. Y

In order to flatten and more perfectly diffuse the water issuing from the jets or perforations into a sheet of water, and `for the protection from passing vehicles of the pipe and perforations, a cap is placed, which projects over the perforations in such a"manner that the water `striking against its underside directs it upon the entire width of the street. The cap being level with the highest part of the arch of the street receives all the injury likely to arise from passing vehicles and prevents dirt and other filth from falling into or being forced in said perforations. j

The flow of water into the perforated pipe is regulated by stop cocks or regulators in the pipe leading from the great water main to the perforated pipe. WhenV it is desirable to wash the street the full flow of water is turned on, being in the highest part of the street and the water flowing from each side naturally finds its way to the gutter` carrying with it the dirt and filth where it is readily collected. When desirable to irrigate only, the regulator is only partially turned on and sufficient water allowed to escape to keep the street in a moistened condition. But to describe my invention more fully I will refer to the accompanying drawings forming a part of this specification, the same letters of reference wherever they occur referring to Alike parts.

Figure l represents asectional view of a street with the washer and irrigator in its position and its connection with the great water main by pipe and regulator together with the cap and the eiect produced by the water from the jets striking against its concave sides. Fig. 2 represents a longitudinal view of the washer and irrigator with the perfor-ations exposed and the position of the protecting cap together with the connections to the great mains &c.

, Letter (A) is a strip of wood grooved out sufficienti to allow the erforated pipe (B) and cap C) to be imbedded therein so that the top of the cap (C) andthe top of the groove (a) shall be level with the crown of the arch of the street (E E E E) and eX- tending the distance desired to be washed or irrigated.

(B) is a pipe with two rows of perforations therein as at (I) b) and extending the 4distance desired to be washed and irrigated.

(C) is a cap with two of its sides concave and so constructed that it shall lay upon and be connected to the perforated pipe (B) and present a fiat surface, nearly fill-ing up the top of the groove (A) through which spaces it is intended that the water shall pass after striking the concave sides of the cap (C) as is shown at (c c).

(F) is the great water main.

(Gr) is the connecting pipe from (F) to the regulator (H) which controls the: amount Vof water desired to be used. Vhen the regulator (H) is open the water rushes up the pipe (G) into the pipe (B) thence through the perforations (b b) when it strikes against the concave sides of the cap (C) and is thrown through the apertures (c c) on to the pavement (E E E E) fronr whence it runs naturally to the gutter.

The advantage arising from the position of the pipe and cap will be readily perceived as it offers no obstruction to the common use of the street nor does it incommode passers by while it is in operation.

I do not claim a perforated pipe as a sprinkler as they have been used for many years attached to carts by hand &c., but

Vhat I do claim and desire to secure by Letters Patent is y l. The cap (C) with its concave sides JAMES P. ELLICCTT.
